We can use the VSEPR model to predict the geometry of most polyatomic molecules and ions by focusing only on the number of electron pairs around the central atom, ignoring all other valence electrons present.

For a molecule (or ion) with an AB3E2 pattern, the electron pair geometry is trigonal bipyramidal, and its 3-D shape is T-shaped according to VSEPR theory.. Based on the AB3E2 pattern you provided, we can determine the electron pair geometry and 3-D shape of the molecule (or ion) using VSEPR (Valence Shell Electron Pair Repulsion) theory. In the AB3E2 pattern, A represents the central atom, B ...

SOCl2 3+ (6-4)/2=4,说明分子式AB3E1型,即三对价电子1对孤电子,就是三角锥型.注意的是S才是中心原子,配位原子一共三个（一个O两个Cl）,未成对电子数O2个,Cl共2个. 解析看不懂？ 免费查看同类题视频解析.

ab3e2型粒子（e为孤电子对），应将孤电子对放在双锥体的三角平面内： （1）试写出NSF和产物A、B、C的Lewis结构式。 （2）预期A、B、C中哪一个N—S键最长？

2021年8月17日 · To use the VSEPR model, one begins with the Lewis dot picture to determine the number of lone pairs and bonding domains around a central atom.

AB3E type of molecule has total 3 bond pairs and 1 lone pair around the central atom. Hence, the molecular geometry is Trigonal pyramidal. AB3E2 type of molecule has 3 bond pairs and 2 lone pairs around the central atom. Therefore, the geometry of molecule is ‘T shape or Angular’.

There are no stable ABE4, AB3E3, AB2E4 or ABE5 molecules. All bonds are represented in this table as a line whether the bond is single, double, or triple. Any atom bonded to the center atom counts as one domain, even if it is bonded by a double or triple bond. Count atoms and lone pairs to determine the number of domains, do not count bonds.
